Mazda CX-80 vs BYD Sealion 8

What's the difference?

The Mazda CX-80 Touring G40e will do everything you ask of it and outside of pricey ongoing costs, there’s not much to annoy. It’s too large for my small family of three and if it’s kid stowage that you’re looking for, a people mover might offer better practicality and comfort than what this does. Would it be a model that you jump through hoops to get? Maybe not, but it still has a place as family hauler and is easy to drive.

There’s quite a bit to like here. There’s plenty of equipment, and lots of choice in price, trim level and mechanical complexity.

The driving dynamics are fine if you’re not looking for anything sporty although the performance offered by the dual-motor variants must be considered excessive, even if it’s pretty exciting the first time.

Perhaps what’s missing from the Sealion 8 experience is anything that stamps the car as something special within its hotly-contested market segment. Which is another way of saying it offers up the same limitations, most notably in the third row accommodation and access.

You only need to drive a one-box people mover and utilise the rearmost seat, to understand that the two-box SUV, while a pretty marketable thing, is compromised once the passenger count exceeds five. Nothing new there, but nothing new in the BYD, either, to change that narrative.

At which point, the front-wheel drive variant emerges as the most pragmatic choice and probably the one that meets all the important family tasks headed its way for the smallest outlay.

I've said it before but Mazda SUVs all look like scaled versions of each other to me and the CX-80 looks ridiculously similar to every other larger SUV model in the Mazda stable with the long pronounced nose that features sharp LED lighting and its general robust size.

The rear is where it differs with the proportions becoming a little bulbous but it’s practically shaped and overall is a nice-looking family SUV at the kerb side.

Head inside and the interior is pleasant with its high-quality trims and heavy-handed styling that matches the exterior dimensions with big panelling and air-vents up front to balance out the long width of this dashboard.

However, the whole car tends to lack personality for a model that’s a part of Mazda’s ‘premium SUV’ range. It's nice but doesn't add anything new.

BYD has done its best to give the Sealion 8 its own character and vibe. In fact, it’s a pretty smart looking thing - although still very much a two-box wagon concept - and that’s no given when you consider how much some big SUVs can start to look like large blobs of nothing when you look closely.

There’s the usual Darth Vader stuff at the front, but in profile, the diagonal vent across the front door makes a bit of a statement. The 'plaited' motif of the tail-lights might be stretching things a bit, though.

Inside, the modern board-room feel is invoked by the angular lines and high-tech look and feel of the large info-screens. The panoramic sunroof of the Premium grade also helps brighten up an otherwise pretty dark space.

Seven-seat SUVs tend to really be a 5+2 combo, where the rear two seats are for kid- or emergency-use only. You'll be pleased to find that all passengers enjoy a decent amount of space in each row in the CX-80. The third row is still a little cosy for an adult but my 6ft2 brother managed to get back there without too many grumbles. However, we all giggled as he sort of fell in due to the lack of handholds (sorry, Mack).

Otherwise, the 170mm ground clearance and wide door apertures make it an easy SUV to get in and out of. The doors are heavy and sometimes miss their 'hold' position if you open them too quickly, making them swing back. My eight-year-old got whacked a few times because of it!

Amenities and storage are best in the first and second rows with front occupants enjoying those heated seats, two USB-C ports, a 12-volt socket and wireless charging pad. You also get dual-zone climate control, and powered seats with adjustable lumbar support. The seats are well-padded but fairly narrow and short in the base, making it easy to fatigue on longer journeys.

Storage includes a large glovebox that can hold a manual and a fair bit more, a shallow but handy middle console because of its dual-opening lid and a total of four drink holders. There's a sunglasses holder but not much else for smaller loose items.

In the second row you get two map pockets, a small storage bin in each door and a total of six drink holders. There's also individual reading lights, two USB-C ports, climate control, directional air vents, a fold-down armrest and retractable sunblinds (always a winning feature in my house).

The third row gets four drink holders, two USB-C ports and two directional air vents.

Feedback from my passengers (kids and adults alike) hasn't been great for the air-conditioning system with all complaining how long it took for the rear two rows to cool down. The low and awkward positioning of the air vents also prevents direct air flow to passengers. The third row is impacted by this as the passenger's legs cover them.

The rest of the technology is solid with the multimedia system offering a rotary dial operation. The system hasn't seen any recent updates, so if you're familiar with the Mazda system, you'll get along just fine.

The built-in satellite navigation is simple enough to use and the wireless Apple CarPlay is easy to connect to. There's also wireless Android Auto. Call connections remained consistent but feedback was that there seemed to be a fair bit of background noise on my end during calls.

Rounding out the interior is the boot space which offers a level loading space, retractable cargo blind and underfloor storage which houses the tyre repair kit. There's also a 12-volt socket and 220-volt/150W AC socket housed on a side panel.

With all three rows up, you get 258L of capacity and that figure jumps up to 566L when the third row is stowed. The CX-8 offered more boot space but the CX-80 is still respectable for the annual family road trip. Plus you get a powered tailgate function in the Touring model, which is always appreciated.

BYD has made sure all three rows of the Sealion 8 are fit for purpose while attempting to make the rearmost row (traditionally the trickiest to get right) less of a downmarket place to be. With that in mind, both rear rows get air vents and climate-control adjustment for that part of the car. There's also a pair of USB-C charge ports in the second row and a single USB-C and USB-A port in the third row. The third row also has cupholders bult into the wheel arch on each side.

With the third row in place, there’s a decent amount of luggage space (270 litres) largely thanks to the Sealion’s five-metre overall length. There’s no spare tyre, but a puncture repair kit lives under the floor (as does the removable cargo blind) and the rearmost luggage space also incorporates a 12-volt socket and luggage hooks.

A pair of pull-tabs drop the headrests and then the entire split third row in a single movement, at which point you suddenly have a five-seater with a huge, 960 litres of luggage space. And if you need to cart gear over people, the second row also folds flat to open up 1960 litres of space.

Up front, the feeling of spaciousness is amplified due to the low scuttle height and what the aviation industry calls the glass cockpit (no analogue dials or gauges at all). The 15.6-inch central info-screen runs the usual apps and control displays but, thankfully, the climate control touch-controls are tethered to the bottom of the screen, so they’re always visible regardless of what else is going on.

The 10.2-inch driver’s display adds a head-up function in Premium trim and displays the usual array of information required to operate the vehicle. But even better is the steering wheel which features a thick, well-padded rim that looks and feels pretty luxe. It also houses the usual buttons for stereo, phone and cruise-control functions.

A really nice touch is the addition of an extra set of tilt controls on the inside of the passenger’s front seat, allowing the driver to control that seat to allow people in or out without leaving their own seat. Nice one.

It is, of course, the centre row of seats that will make or break a car like this for many families. Even though many clans will not use the rearmost seat much of the time, the central row will get a huge workout. So it’s nice to see that leg, foot and headroom are all sufficient for even growing teenagers. Again, the car’s overall length appears to be the key, but it’s also worth noting the centre row seat is comfy and supportive. The outboard positions in the second row also feature heating and ventilation functions.

The third row, however, follows SUV tradition by being strictly for smaller kids. Access past those huge wheel arches is tight, and once you’re in, there’s a combination of dark trim and tiny windows to limit joy.

While it won’t matter to many buyers, the front-drive Sealion 8 is rated to tow 1800kg with a braked trailer, and up to two tonnes in the all-wheel drive version. But there’s no spare tyre fitted, and roadside flats need to be addressed by the included tyre repair kit.

BYD will offer the Sealion 8 in three trim levels, starting with the front-drive Dynamic at $56,990, before on-road costs, then moving to a pair of all-wheel-drive variants, the first with the same Dynamic trim level at $63,990 and the range-topping Premium AWD at $70,990.

The Dynamic trim level on both the front-wheel drive and the all-wheel drive variant gets you three-zone climate-control, air vents in both rear rows, full connectivity including wireless Apple CarPlay and Android Auto. There’s also wireless phone charging. The Dynamic specification also takes on 20-inch alloy wheels and there’s full LED lighting as standard.

Pony up for the Premium trim and you make the switch to 21-inch alloys, a 21-speaker sound system and even a massage function for the first two rows of seats. The Premium also includes a head-up display for the driver.

Not as easy to quantify is the level of plush inside the cabin. There are lots of soft-touch surfaces and the whole interior design looks pretty fresh and modern and well put together. But more than that, there’s a bit of design flair that makes the BYD feel perhaps a bit more expensive than it really is. That’s not an easy thing to pull off. But it seems to work here, even in the entry-level Dynamic trim.

Against the competition, the Sealion 8 can't match the similarly specified Chery Tiggo 8 on price, even though on performance and EV range, the Tiggo 8 and the entry-level Sealion 8 are quite similar. The more expensive Sealion 8 Premium, meanwhile, lines up pretty neatly on price with the Kia Sorento S PHEV. But that vehicle can't get close to the epic straight-line performance of the BYD.

 The CX-80 Touring G40e model has an eight-speed auto transmission and all-wheel drive via a 3.3L turbo-petrol in-line six-cylinder engine coupled with a 48-volt mild hybrid system that produces up to 209kW of power and 450Nm of torque.

It’s not ridiculously powerful but pick up is great and there's more than enough to move the CX-80's big body around and support a 2500kg braked towing capacity.

BYD has managed to keep a lid on the price of the entry-level version of the Sealion 8, by specifying it with front-wheel drive rather than the all-wheel drive of the other two variants. It still gets the same driveline beyond the lack of a driven rear axle, although battery capacity is the other difference.

As such, you’re looking at a 1.5-litre petrol engine (kind of the default powerplant for Chinese SUVs right now) with a turbocharger. With the 19kWh battery chiming in to power the electric motor, the driveline can achieve outputs of 205kW and 315Nm.

In the case of the AWD variants, the larger 35.6kWh battery and extra electric motor ups the potential outputs to 359kW and 675Nm which is a huge jump any way you look at it and gives the Sealion 8 a huge bandwidth when it comes to matching buyer performance aspirations.

All the variants have the potential for a claimed electric-only range of greater than 100km if owners use the plug-in facility to charge either at home or at work. For the AWD variants, the larger battery stretches the EV range to a claimed 152km. On longer journeys or whenever the battery has reached about 25 per cent capacity, the Sealion 8 acts just as any other hybrid with regenerative braking and electric assistance to aid performance.

In suspension terms, the BYD is pretty conventional but if you do pay the extra for the Premium variant, you’ll gain adaptive dampers.

The Touring G40e model has a 74-litre fuel tank and an official combined fuel cycle usage of 8.4L/100km, which gives you a theoretical driving range of up to 880km.

The mild-hybrid system works well enough that I didn’t hit double digits for fuel usage despite not being shy on using the power while hauling cargo and people on a mix of open road and urban trips.

My real-world use popped out at 9.3L/100km and while the diesel variant has much more efficient outputs and range, this result is pretty good for such a massive SUV.

BYD claims a range of more than 1000km for both variants of the Sealion 8, provided you start with a fully charged battery and a full 60-litre fuel tank.

The BYD can also make use of commercial fast-chargers and, when using the maximum 40kW on the FWD version and the 74kW possible for the AWD variant, the charging times from 30 to 80 per cent are both under 20 minutes. The Sealion 8 can also charge at 11kW on an AC socket and the vehicle also offers V2L (Vehicle to Load) capability, meaning it can power on-site work tools, camping gear or even your house at night.

Provided the EV battery is kept at 25 per cent capacity or above, BYD claims a 1.0-litre per 100km fuel consumption figure for the car based on the laboratory test. In the real world, the results will vary enormously depending on where you drive and how the car is used. Deplete the battery and continue to drive at highway speeds, and your actual fuel consumption might easily increase to many times that 1.0-litre claimed figure.

The Touring G40e model is pleasant, if a little boring, to bum around in. Boring may be too strong a word but there's not much that gets you excited about the driving experience. The Touring performs and has decent power through most situations but it lacks a certain edge. It's not particularly sporty, nor does it sound mean when you put your foot down.

It's nice and does what you expect it to do.

The ride comfort is good with cushioned suspension with enough road feedback but people in the back will jostle a bit over the worst of the bumps.

Road noise can creep in at higher speeds and third rowers will struggle to be a part of the conversation but overall the cabin is refined for longer journeys.  

Visibility is mostly good because of the big windows but the wider pillars mean I check my blind spots very carefully, as the side mirrors seem a tad too small for the bulk of the car.

The CX-80 has a small turning circle of 11.6m and most of the time it never feels like it lumbers, but when you’re manoeuvring it in a tight car park the steering can feel heavy and a three-point turn starts to feel clumsy.

A saving grace is the excellent quality of the 360-degree camera system which takes out some of the puff from parking it. The CX-80 fills a space and it’s one you'd be careful to park so you don't get crowded.

The first thing you’re going to do in a Sealion 8 is wonder where the gearshift is. It’s a column-shift, but it's not only located where a traditional indicator stalk would be, it looks very much like one, too.

This promises two things. One, you’ll spend a few seconds finding it and two, you’ll try to turn the indicators on with it at least once every drive. (The real indicators are on the other side of the steering column.)

Another note to those test driving a Sealion 8. Sample the front-drive version first. (I’ll get to why in a minute.) When you do, you’ll soon figure out this is a driveline that prioritises electric running. That is, the petrol motor barely ever actually drives the wheels (only at full throttle and higher speeds). Any other time, if the petrol engine is running, it’s to charge the battery that keeps the electric motor purring away. This is how efficiency is defined by BYD.

You’ll also find that the Sealion’s acceleration is purposeful in that electric-motor way, but hardly startling. And when you do smash the throttle and force the petrol engine to drive the axle, you’ll notice that this takes a fair time to play out, and that when everything is grunting as hard as possible, the petrol engine is quite noisy and even a little harsh sounding. Use the driveline sensibly, though, and it’s all smooth and quiet, even if that then means you can hear a little suspension noise creeping into the cabin.

That done, you’re now free to drive the AWD variant. Why wait? Because this thing is seriously off the leash. Bear in mind that 359kW of power is getting on for the thick end of 500 horsepower in the old money, so even though the Sealion 8 is a hefty critter at about 2.5 tonnes, all that power and torque will get it from rest in under five seconds, or thereabouts. The relevance of this to family-car technology is hugely debatable, but it’s one heck of a party trick the first time you try it.

The huge torque also magnifies the Sealion 8’s natural tendency to lift its inside front wheel when accelerating out of a turn. A small tyre squeak can sometimes be heard before the traction control gathers it all together, but even the single-motor variant displays the same trait.

In steering and suspension terms, it’s probably fair to say the Sealion 8 doesn’t unlock any new depths of talent. The ride is pretty comfy but at the expense of body control and the steering points the wheels but doesn’t convey much else to the driver.

That said, the fact everything seems to be tuned to the same frequency means it all works okay. You don’t have too-fast steering fighting the tyres or too firm suspension upsetting the interior calm. Use it as a family would, and it’s 100 per cent fit for purpose.

Any family car needs to be safe, so BYD has thrown the kitchen sink at the Sealion 8 in terms of its active and passive safety gear. That starts with nine air-bags including full-length curtain side bags and a centre-front airbag to help prevent head clashes.

There’s also a 360-degree camera on all grades, front and rear parking sensors, and the full line-up of current driver-assistance functions including autonomous emergency braking, lane-keeping assistant, rear-cross-traffic alert and assistance, blind-spot monitoring, driver attention monitoring and a tyre-pressure monitoring system.

To that lot, you can add adaptive cruise-control, traffic-sign recognition, adaptive headlights, front and rear collision warning, anti roll-over systems and hill-hold functions. It’s also worth mentioning that the overhead camera system is very, very good with a clear, crisp display and no processing delay.

The driver-attention monitoring seems to behave itself better than some of the over-active systems other makers specify, but the lane-keeping assistance function is still far form perfect. To be fair, it is less aggressive than some such systems and the intervention is more subtle, but the recued aggression seems to be packaged with lower sensitivity. As in, the cameras seem to sometimes miss a critical white line, particularly if its faded or less than freshly painted.

There are also ISOFIX child restraint tether points in both the second and third rows, as well as seat-belt warnings for every position and an electronic child-safety switch for the doors.

The Sealion 8 is yet to be crash tested locally, so no ANCAP star rating is available.

The CX-80 is let down a bit by its ongoing costs.

Mazda offers the CX-80 with a five-year/unlimited kilometre warranty which is fairly standard. A number of its rivals are offered with up to seven-year terms these days.

You get a five-year servicing program with services averaging $694, which makes it on the more expensive side, but servicing intervals are reasonable at every 12 months or 15,000km, whichever occurs first.

Servicing any hybrid can be a bit more expensive thanks to the presence of two propulsion forms.

In any case, the Sealion 8 requires routine servicing every 12 months or 20,000km.

Warranty is BYD’s normal six-year/150,000km cover, although there’s also eight years and 160,000km of cover for the EV battery.

BYD also claims its 'Blade' battery technology is among the safest in the business, and says the design resists damage (and, therefore, the risk of fire) better than the competition.
